A new evaluation model for human-computer interaction

In order to evaluate human-computer interaction systems, we improved the heuristic evaluation, and develop a new evaluating model, which is the meta-synthesis of Delphi approach, analytic Hierarchy process, and Fuzzy evaluation (DHF). The theory foundation of the evaluating model is meta-synthesis method from qualitative to quantitative. Using the methods, the accuracy of evaluation was estimated, and a practical example for accuracy of model was given. It is shown DHF can be used to evaluate human-computer interaction systems.
